* dynobj.cc (Sized_dynobj::setup): Take a Target object instead of an elcpp::Ehdr as parameter. Adjust call to set_target. * dynobj.h (Sized_dynobj::setup): Take a Target object instead of an elfcpp::Ehdr as parameter. * object.cc (Object::set_target): Remove the version that looks up a target and sets it.
